Catmint

This non-culinary mint variety is a showy perennial that will bring pleasure to you—and your cat—for years to come. Blooming in early spring, it is easy to grow and tolerates both heat and drought. You don’t need to do a thing for it, although if you prune the flowers after they’re spent, you may get another show later in the season. Available from Burpee; $9.95 per plant.
